DIE BOX FOR WIRE-DRAWING MACHINERY.

Application filed March 11, 1922. Serial No. 543,032.

To all whom 2'1- may. concern:

Be it known that we, JEROME R. GEORGE and VILLIAM E. CARROLL, both citizens of the United States, residing at \Vorcester,

55 in the county of 'orcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Die Boxes for Tire-Drawing Machinery, of which the following, together with the accompanying I drawings, is a specification.

The present invention relates to the boxes that are used for'holding the dies employed in the drawing of wire. And more particularly, the invention contemplates the provision of a die box or holder wherein improved means for retaining thecpowdered soap or other lubricant are provided, thereby eliminating the need for constant replenishment of said lubricant which, in the ordi- .20 nary die box construction, escapes continuously from the interior of the box.

The several features and advantages of our improved constructionare set forth in detail in the following description, reference being'had to the accompanying drawin whereinig. 1 is a view'in side elevation of our improved die box. h

Fig. 2 is an end elevation of same. Fig. 3 is a top plan view of same.

Like reference characters refer to like parts in the different figures.

In the ordinary die box construction, the die is disposed directly in the chamber #5 which contains the powdered soap or other lubricant. said die -being entered through an opening provided in the side wall of said chamber. This lateral opening must be of sufiicient. size to receive the largest die to G0 which the box is adapted, and heretofore it has been the practice. after the fixing of the die in place, to plug up said opening with waste and the like in order to prevent, as

far as possible, the escape of lubricant from the interior of the box. Such an expedient is unsatisfactory andextremely wasteful of time, particularly when the dies have to be frequently changed.

According to the present invention, the

ll above mentioned diflicu'lties are overcome by the provision of a separate retainer for the powdered soap or other lubricant. the

die itself being wholly outside of this retainer, so that the latter can present unbroken side, bottom and end walls, except for the small holes through which the wire is passed. As shown in the drawings, the die holder proper, represented generally by the numeral 1, has the usual front wall 2, against which bears the die 3 resting upon a block or wedge 4; Behind the .die 3, the

holder 1, supports an independe'ntrcc'eptacle 5, the latter having side walls 6, 6, a bottom 7, and end walls 8 and 9 which inclose a chamber for the retentionof powdered soap. From this receptacle 5 there is no appreci able escape or loss of the lubricating material; although the front wall 9 has an open.- ing for the passage of wire', the soap has no outlet therethrough. because the wire fills the die passage with which said opening communlcat'es. I p

' The receptacle 5 serves as a means for retaining the die in position in its holder in the following manner :At its 'rear end, the

holder 1 provides bosses 10, 10, having apin 13 in the forward set of holes 12, 12', 4

thus bringing the arm 15 into juxtaposition tothe rear wall 8 of the soap receptacle. The other arm 1470f said bell crank is acted upon by a screw 16, disposed in a threaded opention of the soap receptacle 5. In this position of'the parts, the action is preclsely the same, since the free end of arm 14 remains under the influence of screw 16. Asshown in Fig. 1', a washer 19, of suitable yielding materiah; is preferablv interposed between the die 3 and the front wall 9 of soap receptacle 5, to prevent any escape of soap which may be drawn forward against the rear face of the die. The opening 20 through the front wall 9 of receptacle 5, for the passage of the wire to the die, is preferably tapered. as shown in Fig. 1, to conform substantially to the taper at the large end of the die opening, whereby to guide the wire and facilitate its insertion into the last named opening.

\Ve claim,

1. The combination with a box or holder for a wire-drawing die, of means associated therem 1th for isolating the wire-drawing lubricant from the die containing space of said b x. 2. The combination with a box or holder for a \\irc-drawin; die. said box having a side opening for the insertion of said die, of means for preventing the access of wire drawing lubricant 'to said opening.

3. The combination with a box or holder for a wire-drawing die. of an independent receptacle within said box for the retention and isolation of the wire-drawing lubricant.

. The combination with a box or holder for a wire-drawing die, of an independent receptacle within said box for the retention and isolation of the wire-drawing lubricant, and means for applying the retaining force on said die through said receptacle.

5. The combination with a box or holder for a wire-drawing die; of an independent receptacle within said box for the retention and isolation of the wire-drawing lubricant, and means for applying the retaining force on said die through said receptacle, said receptacle being adjustable within the die box to accommodate diiterent sizes of dies, and said force applying means being correspondingly adjustable.

6. The combination with a box or holder for a wire drawing die, of an independent member within said box having an opening next the die for the passage of a wire, a compressible ring or seat interposed between said member and the die, and means for forcing said member against the die to hold it in place,
